Circuit Zandvoort Track Insights 14 – Arie Luyendykbocht

Immediately after the important Kumhobocht, the last corner of Circuit Zandvoort follows reasonably quickly: the Arie Luyendykbocht. The bend has undergone a major metamorphosis and has been transformed into an impressive banked corner with an 18-degree banking, including a SAFER barrier.

▲ The Arie Luyendyk curve has practically always been one of the fastest turns at Circuit Zandvoort. The corner was built in 1948 in an area between a large pond and an area of potato fields called “Pulleveld”. The corner got the name “Bos Uit” because the drivers drove out of a small forest when approaching the last corner. At the end of the 60’s this fast section was equipped with guardrails at only a few locations, but otherwise the track was largely fenced off by wooden poles with mesh.

 

▼ Provided the drivers had the courage to properly steer into the turn, they were able to reach very high speeds at the form “Bos Uit” section and then take that high speed up the main straight.

▲ At the end of the 80’s the circuit of Zandvoort was firmly rebuilt and shortened to an Interim circuit. In the same period a holiday resort was built on the location of the former Bos Uit. Because of this, the last corner was moved to another location, but kept the name Bos Uit. The straight of Circuit Zandvoort also became a bit shorter due to this change. The observant viewer can see in the aerial photo of 2018 something of the old Bos Uit as it was used until 1989. In the middle of the picture, two white trucks are parked on the old asphalt from that period. In the line of those trucks one can see red and white painted kerbstones, marking the inside of the bend at that time. In 2001 the name of the bend was to change to Arie Luyendykbocht, as a tribute to the double Indy 500-winner and at that time “fastest Dutchman in the US”.

▼ In the year 2020 the Arie Luyendykbocht has changed a lot. Not only the gravel bed has disappeared, but the turn itself has been completely transformed into an impressive banked corner. The Arie Luyendykbocht makes it possible to race at a higher speed towards the finish line and Tarzanbocht, thanks to a gradient of 15-18 degrees (a maximum gradient of 32%) in the banking. It is also expected that the number of slipstream fights on the straight and overtakes at the Tarzan curve will increase. On the outside of the bend a special SAFER barrier has been placed. Thanks to the combination of a closed steel barrier construction with special foam elements, the SAFER barrier absorbs the energy released during a crash. The forces and energy a driver experiences in this process are considerably lower than in previous incidents. The closed construction also ensures that the damaged cars can slide through to a safer location at the end of the bend. SAFER barriers are also used on almost all American oval circuits. Directly next to the SAFER barrier is the new FIA safety fence.

▲ The new Arie Luyendykbocht from a different perspective. At the bottom of the picture you can also see the new pedestrian tunnel. This connects Parking C and the outer ring road with the south side of Paddock 2. At the top left is the new Champions Lounge, while the special FlyingDutch asphalt, developed by circuit designers Dromo and VolkerWessels, moves towards the straight like a nice grey line.
